The title complex, [CuCl(C4H8OS)]n, contains infinite spiral (CuS)n chains linked by bridging Cl atoms into layers. The Cl atoms do not form polymeric fragments with CuI, but combine into isolated centrosymmetric Cu2Cl2 units. The compound is non-isomorphous with the Br-containing analogue, which contains Cu8S8 rings linked by Br atoms into chains. The O atom of the 1,4-oxathiane molecule does not realize its coordination abilities in the known copper(I)-halide complexes, while in copper(II)-halide complexes, oxathiane is coordinated via the S and O atoms. This falls into a pattern of the preferred interactions, viz. weak acid (CuI atom) with weak base (S atom) and harder acid (CuII atom) with harder base (O atom).
